Experts tab is rubbish and i was fortunate enough to stumble across this EXCELLENT post by 7bit; it's made debugging so much more powerful :)

Addendum: Writing to Experts tab also creates log files, which over time can slow down the terminal. To optimise speed, go to Tools->Options->Charts and change both Max bars to 500, so the terminal isn't constantly pulling thousands of candles from the server and delete old log files.
